OSCILLATING ENGINE-VALVE.

Specification of Letters Patent.

Patented July 30, 1918.

Application filed March 19, 1918. Serial No. 223,446.

To all whom it may concern:

Be it known that I, ERNEST R. McIN- Turn, a citizen of the United States, residing at Bealeton, in the county of Fauquier and State of Virginia, have invented new and useful Improvements in Oscillating EngineValves, of which the following is a specification.

This invention relates to oscillating valve structures especially adapted to be used upon hydrocarbon explosive engines, and it consists in the novel features herein after described and' claimed.

An object of the invention is to provide a valve of the character stated which is of simple and durable structure and having its parts so arranged that the valve proper will remain in close contact with the wall of the casing and thereby prevent leakage without the use of washers or packings.

lVith the above object in view the valve includes a cone-shaped casing fashioned upon the head of the cylinder and having an intake port and a plurality of exhaust ports.

cone-shaped valve member is turnably mounted in the casing and provided with ports adapted to be brought at times in register with the intake and exhaust ports in the usual manner. The valve member is further provided with an opening through which the s ark from a spark plug may pass when the discharge of gas is ignited at the time that it is fired. Means are timed up with the engine shaft to oscillate the valve member to bring the ports of the members into register with the intake and exhaust ports at proper intervals of time.

In the accompanying drawings:-

Figure 1 is a fragmentary top len view of an engine with the valve app ied;

Fig. 2 is a transverse sectional view of the valve;

Fig. 3 is a similar view out on a plane at a right angl to the view shown in Fig. 2;

Fig. 4 is a horizontal sectional view of the same cut on the line 4-4 of Fig. 3.

Fig. 5 is a fragmentary view of a cam member adapted to operate the valve member;

Fi 6 is a perspective view: of the valve mem r. I

The cylinder head 1 is provided with a centrally located con'e-sha ed' casing 2 I which may be provided at its side with a plurality valve member 5 fits snugly in the casing 2 v and is provided with a port 6 adapted to be brought into register with the port 3 and ports 7 adapted to be brought into register with the ports 4 during the operation of the engine in the usual manner. The member 5 is provided with an opening 8 through which a spark plug 9 maypass when the charge of gas is ignited. The valve member 5 is provided with a stem 10 which passes centrally through the topof the casing and an arm 11 is fixed to the upper end of the stem 10. The arm 11 carries at its free end a roller 12 which is received in an annular groove 13 of a disk 14 mounted upon a shaft 15 which in turn is operatively connected with the shaft of the engine by means ofa belt 16 in a usual manner. The groove 13 is provided with oppositely disposed cam portions 17 and 18 best shown in Fig. 5 of the drawing. These portions are disposed on the opposite sides of the major portion of the groove 13, consequently when the roller 12 moves into the cam portion 17 the arm-11 is swung in one direction and when the roller 12 moves into the portion 18 the said arm 11 is swung in an opposite direction. As the arm 11 is swung as hereinbefore indicated the valve member 5 is turned in the casing 2 so that the ports 6 and 7 are brought into register at proper times with the ports 3 and 4.

The spark plug 9 may be timed and operatively and electrically connected with a source of energy whereby it will produce a Spark when the charge has been com ressed in the en 'ne cylinder and therefore t e said charge Wlll be fired at the proper time and in a usual manner.

From the foregoing description taken in conjunction with the accompanying drawing, it will be seen that an oscillating valve of simple and durable structure is provided and that the same may be economically used upon a hydro-carbon or gas engine and that the parts of the valve are so arranged as to prevent leakage from the cylinder of the engine and in the absence 0 packings or gloacking glands.

I aving thus described the invention what is claimed is A valve comprising a casing which is approximately cone shaped, said casing having an intake and an exhaust port, a truncated cone shaped valve member fitted snugly in I the casin and having ports adapted to regis- 10 ter at di erent times with the intake and exhaust ports of the casing, said member having at its side a spark opening located at a point between the intake and exhaust ports of the valve member and a stem connected 16 with the smaller end of the valve member.

In testimony whereof I aflix my si nature.

ERNEST R. McINTU FF.
